The project started as a 1 meter Cartesian Cube. But for easy transportation around the house, I had to reduce the printer width to 83 cm from 1 meter.
Printer details can be found below ;
Max tested printing speed : 150mm/s
Best results as of now : 75mm/s with 550 acceleration & 0.04 junction Deviation
Printer dimensions :
Length : 120 cm
Width : 83 cm
Height : 83 cm
Current Print Dimension :
60 × 60 × 50 cm
Print Dimension upgradable :
120*83*83 cm
Endstops set to : 48x * 38y * 28z cm
Firmware :
